EVA SIP Phone is a SIP-based softphone developed by Verysoft, a company with almost a decade of VoIP development experience. It is a part of a new generation VoIP platform that was optimized for WiFi, 3G, and LTE and designed to provide customers with the best audio quality even on poor channels while saving battery life. EVA SIP Phone is fully compatible with SIP providers and other softphones. It is currently available for Android devices only and is free to download.

One of the main features of EVA SIP Phone is its ability to place voice calls using the SIP protocol. However, it is important to note that it is not a VoIP service, so it requires a SIP account to make calls.
